THE parents of a Harrow youngster whose death has never been solved hope a documentary on their personal investigation will help finally bring justice for their son.

On April 1 Channel Four's Cutting Edge series will broadcast Lost Abroad: The Parents' Story – which looks at Erica Duggan's pursuit to get answers about her son Jeremiah's death.

Former Quainton Hall School pupil Jeremiah, 22, was found on a dual carriageway on the outskirts of Wiesbaden, Germany, in 2003, just five days after he arrived in the region.

Shortly before his death, Jeremiah made several phone calls to his family and girlfriend indicating that he believed his life was in danger but authorities in Germany claimed his death was not suspicious.

Police claimed it was suicide but his family have been pressing for a full investigation after collating evidence that they say shows the young Jew was beaten to death by members of alleged antiSemitic cult, LaRouche.

Saturday marked the seventh anniversary of his death and speaking to the Observer this week Mrs Duggan said: "This time of year is obviously horrible for the whole family and I wouldn't have even been able to speak on Saturday.

"We hope the documentary will highlight how painstaking our attempts to seek answers have been and if it can help in our pursuit for justice then it will be well worthwhile.

"We have been sent letters of apology from those involved in his hasty inquest and we are awaiting a date for an investigation to be held at High Court.

"It has been an incredibly hard seven years for us and we are still left with so many unanswered questions."

The Channel Four film crew followed Mrs Duggan to Wiesbaden last year as she walked the route Jeremiah supposedly ran in the 20 minutes before he died.

They also followed the family of 22-year-old Lindsay Hawker, who was tragically found buried in a bath of sand in Tokyo in 2007.
